Add and register a function to check if the device has been remounted
since last update during incremental OTA. This function reads block 0
and executes before partition recovery for version >= 4.

We are already using O_SYNC and fsync() for the recursive case
(package_extract_dir()). Make it consistent for the single-file case.

Add block_image_recover function to rewrite corrupted blocks on the
partition. This can be attempted if block_image_verify fails.
Note that we cannot use libfec during block_image_update as it may
overwrite blocks required for error correction. A separate recovery
pass in case the image is corrupted is the only viable option.

We have the last line being empty as a result of
android::base::Split("a\nb\n"), which leads to "missing command"
warnings in the update. Just skip all the empty lines.

When processing ui_print commands in the updater, it misses a line break
when printing to the recovery log.
Also clean up uiPrintf() and UIPrintFn() with std::string's.

There is an integer overflow when the size of system goes beyond the
signed int limits. Hence changing pos to size_t.

Currently the fsync() inside write_all() may be called multiple times
when performing a command. Move that to the outer loop and call it
only after completing the command.
Also remove the O_SYNC flag when writing a stash.

This reverts commit b65f0272c8.
It slows down the update too much on some devices (e.g. increased
from 8 mins to 40 mins to take a full OTA update).

A RangeSet has half-closed half-open bounds. For example, "3,5" contains
blocks 3 and 4. So "3,5" and "5,7" are actually not overlapped.

Due to observed BLKDISCARD flakiness, overwrite blocks that we want
to discard with zeros first to avoid later issues with dm-verity if
BLKDISCARD is not successful.

Although stdout and stderr are both redirected to log file with no
buffering, we are seeing some outputs are mixed in random order.
This is because ui_print commands from the updater are passed to the
recovery binary via a pipe, which may interleave with other outputs
that go to stderr directly.
In recovery, adding ui::PrintOnScreenOnly() function to handle
ui_print command, which skips printing to stdout. Meanwhile, updater
prints the contents to stderr in addition to piping them to recovery.

In the block updater, if BLKDISCARD fails, the error is silently
ignored and some of the blocks may not be erased. This means the
target partition will have inconsistent contents.
If the ioctl fails, return an error and abort the update.

These are already getting libc++, so it isn't necessary. If any of the
other static libraries (such as adb) use new or delete from libc++,
there will be symbol collisions.

When automatically stashing overlapping blocks, should the stash
file already exist due to an explicit stash command, it's not safe
to remove the stash file after the command has completed.
Note that it is safe to assume that the stash file will remain in
place during the execution of the next command, so we don't have
take other measures to preserve overlapping blocks.
The stash file itself will be removed by a free command when it's
no longer needed.

I've added explanatory comments to mzExtractRecursive because
that function will live on as a utility even after we move the
zip format related logic to libziparchive.

Add support for transfer list version 3, which allows us to
verify the status of each command and resume an interrupted
block based OTA update. Notes on the changes:
- Move the previous BlockImageUpdateFn to a shorter and
reusable PerformBlockImageUpdate, which can be used also
in BlockImageVerifyFn for verification.
- Split individual transfer list commands into separate
functions with unified parameters for clarity, and use
a hash table to locate them during execution.
- Move common block reading and writing to ReadBlocks and
WriteBlocks to reduce code duplication, and rename the
readblock and writeblock to less confusing read_all and
write_all.
The coding style of the new functions follows the existing
style in the updater/edify code.
